所以我正在做关于电影订购系统的作业。给定的那一天应该显示它自己的电影列表，但我得到了另一件事。
整个代码
#include <iostream>

知道为什么会这样吗？我该如何解决？顺便说一句，第一次使用 stackoverflow
输入一天，期待正确的列表出来，错误的列表无法输入看什么电影，代码自行退出并返回值巨大
首先你已经正确检查了
if (Day == "Wednesday)"if (list=1)下一个问题是变量 i 从未被初始化，所以在执行
ticket[i]="Ant-Man and the Wasp: Quantumania 10.00";您的代码中还有许多其他未初始化的变量，将来可能会导致更多问题。
